The matrix converter solid state transformer (MC-SST), formed from the back-to-back connection of two three-to-single-phase matrix converters, is studied for use in the interconnection of two ac grids. The matrix converter topology provides a light weight and low volume single-stage bidirectional ac-ac power conversion without the need for a dc link. Thus, the lifetime limitations of dc-bus storage...
A power management control method is proposed for the three-phase-to-single-phase matrix converter (MC)-based solid state transformer (SST) linking two grids. The MC-SST presents low weight and high controllability with respect to a conventional line-frequency transformer. Moreover, the single-stage ac-ac power conversion and compact volume are achieved compared to a three-stage SST, owing to the...
